Fitzgerald, according to his agent, will play the role of Steven Constantine.

The series concerns "two hosts of a satellite radio show who detest each other but whose chemistry causes ratings to go through the roof." Fitzgerald's character is a "floater at the radio station who's a genius at creating and embracing wildly different characters in his everyday life."

Tony nominee Fitzgerald will next be seen opposite Kristen Wiig and Annette Bening in "Imogene," directed by Shari Springer Berman and Bob Pulcini.
